said bolt for normally urging the bolt against said wall portion 31.

Attached to the door jamb 11 is 'a keeper 40 comprising a plate 41attached to the outer edge of said door jamb, and having an opening 42therein, for receiving the forward part of the bolt. Attached to orformed integrally with said plate 40 is a housing 43 into which theforward portion of said bolt is adapted to project. The plate 41 isprovided with a projecting edge portion 44 and the front surface 37 ofthe bolt 18a is formed with a number of teeth 45 adjacent the outer endthereof adapted to engage said edge portion 44 for the purpose From the'description thus far, it will be seen that if a jimmy were insertedbetween the door and the door jamb for retracting the bolt 18a, saidjimmy would"necessarily contact the rear-surface of the bolt andpressfthe same againstthe edge portion 44 toprevent further retractionof the bolt.

It will be noted that the opening 19in said front wall, 15 is ofsufficient width to permit a slight pivotal orlateral movement oftheboltv necessary for causing engagementfbe tween the teetl 45 and theedge portion 44.

. The prevention'of unauthorized opening of the lock by means of thejimmy insured since'the bolt can only be retracted by Ines sure exertedon the bolt, andsuch pressure necessarilycauses interengagement betweenthe teeth 45'and'the edge portion 44. Thus,

pullingthe door rearwardly while actuating the jimmy will notpermitthebolt to be retracted. w I j "For normally retracting the bolt'18a,however, there is provided the usual knob pivoted to the front wall 13of the casing and provided with an arm 51' adapted to engage aprojection 52 formed on said bolt, so that upon rotating the knob 50,said arm will engage said projection for retracting the bolt. The boltis further provided with a slightly camrned portion 53 adjacent saidprojection '52, so that upon rotating the knobffor retracting the bolt,engagement between the arm 51 andsaid cam 53 will push the bolt towardsaid wall 31' and away from the edge portion 44 to insure properactuation of the lock, Obviously the spring 35 likewise retains the boltout of engagement with said edge portion 44.

The usual key tumbler mechanism 54 may also beprovided, whereby the boltmay be retracted by use of a key. The lug 55a of arm'member 55associated with said tumbler mechanism, is adaptedto be rotated intocontact with projection,-'52' for retracting the bolt. The spring27insures proper project-ion of the bolt after the knob hasbeen releasedor the key removedfrom 'the tumbler. Also .thedoor maybe slammed in theusual man r, the amped portion 20 striking the curved portion 56 of theplate therewith, that the teeth 45 will engage the edge portion 44 tolock the bolt against retraction. 'Upon inserting a key into the tumblerandturning the same, the boltwill be retracted]withoutretardation sinceno external pressure need, beextended toturn th'ekeyJ Y 'A dominantfeature of'theinventioni's the'provision of a latch lock having asing'lebelt, which may be normally actuated] by means of a knob-or a key, andwhich will be jimmyproofi;that is, the bolt will engage a fixed portionof the keeper to prevent the retraction thereof upon exertionfof' pres=sure on said bolt. The provision of the slight pivotalor transversemovement or play for the bolt itself permits engagement of the teeth 45with the edge portion 44.'a1 1 rhentt the 'applic'ationflof a'jim'my tothe bolt will necessarily cause the locking of the bolt.

It will thus blJSQQIl th'at there is provided adevice in which theseveral objects of this invention are achieved, and which is welladapted to meet Asjvarious possibleembodiments; might be made of theaboveinv'ention, and asvarious the "conditions of practical changesmight be made' inlthe embodiment above set forth, it is to be understoodthat all matter herein set forth or shown in the accompanying drawing isto be interpreted as illustrative and not in a limiting sense.
